JAR CAP I Filed Feb. 18, 1956 H. Finyhedse r A llamep:

Y Inuehlor Patented Apr. 27, 1937 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to jar caps and more particularly to screw caps of the type used on mason jars or the like.

An object of the present invention is to provide a cap of the character described in such a manner that the same may be readily unscrewed from the neck of the jar without resorting to a wrench, jar cap remover or other tool.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a side elevational view illustrating the application of the invention.

Figure 2 is a top plan view thereof and Figure 3 is a detail sectional view taken substantially on the line 3-3 of Figure 2.

Referring to the drawing by reference numerals it will be seen that 5 indicates generally a screw cap of the type usually employed on mason jars or the like a portion of which type of jar is shown in the drawing and indicated by the reference numeral 6.

In accordance with the present invention, and in the preferred embodiment thereof the cap 5 adjacent the crown has struck out therefrom as at I spring fingers 8 adapted to be rolled about the adjacent side of a substantial rectangular frame member 9. The member 9 is preferably formed of a single length of wire and is of a size as to receive therein the jar cap 5 as clearly shown in the drawing.

It will be apparent that with the member 9 applied to the cap 5 a suitable grip is provided for the hand which will enable the operator to turn the cap 5 in the direction required for unscrewing the cap from the neck of the jar. It will thus be seen that with a device of this char- 5 acter it will not be necessary to resort to a wrench or analogous tool in order to effect removal of the cap.

Having thus described the invention, what is claimed as new is:

1. In combination, a screw cap having a crown and an integral depending skirt together with fingers struck out from the cap at the junction of the crown and skirt and spaced equi-distantly about the circumference of the cap, said fingers being curved inwardly and upwardly to provide loops; and a single length of wire rod trained through said loops and bent at intervals to provide a substantially rectangular frame structure to be engaged by the hand to facilitate threading or unthreading of the cap relative to the neck of a jar.

2. In a jar closure, the combination of a circular metallic screw threaded cap and a substantially square wire-rod frame disposed about said cap adjacent the crown end of the cap, and said frame having each of its four sides secured to the periphery of the cap adjacent the crown of the latter whereby said frame serves as a handle to facilitate turning the cap on the screw threads thereof.
